Flash Fill: The Fast, No-Compaction Backfill Solution
Flash Fill for Contractors: CDOT-Approved, Fast, and Built for the Job
When speed, compliance, and quality matter, Flash Fill is the go-to backfill material for utility, trench, and void-fill applications. As a CDOT-approved product (on the APL), Flash Fill meets the highest standards for road and infrastructure work. That means it’s not only authorized for Colorado Department of Transportation projects, but it’s also accepted in most municipalities across the state — including the City and County of Denver, Aurora, and beyond.
We supply and deliver Flash Fill from Northern Colorado to Denver, its surrounding suburbs, and down to Castle Rock — ensuring contractors have fast access to compliant material wherever the job takes them.

Why Contractors Choose Flash Fill Over Traditional Backfill
The biggest reason is simple: speed. With Flash Fill, you can get traffic moving again in a fraction of the time.
Rapid Reopen: Finish with a Flash Fill Cap or pour asphalt within 1 hour of placement.
Traffic-Ready in 2 Hours: The cap creates a hardened surface that allows vehicle traffic back in place almost immediately.
Lower Traffic Control Costs: Less time with lane closures means reduced flagging, signage, and crew hours.
Reduced Labor Costs: Faster turnaround keeps your crews productive and frees them for the next job.
Uniform Coverage: Flows into every void without layer compaction — strong, consistent support from day one.
Applications Where Flash Fill Excels
Flash Fill isn’t a niche solution — it’s designed for high-demand, high-speed projects:
Utility Trench Backfilling: Approved for water, sewer, electrical, and telecom trench restoration.
Road Cut Repairs: Bring roads back online quickly while meeting CDOT and municipal specs.
Void Filling: Stabilize sidewalks, slabs, or bridge approaches without settling issues.
Emergency Repairs: Keep crews moving and downtime minimal when fast action is critical.
